When you think about all the big historic movements, from the suffragettes, to anti-apartheid, to sexual equality in the 1960s, all the big political movements had popular mobilisation.

This Saturday his wish will – in part, at least – be granted. Protesters will be taking the climate and energy minister's surname and re-appropriating it as the moniker for the latest day of action at E.ON's proposed coal-fired power station at Kingsnorth in Kent.

Activists will gather to form a human "Mili-Band" around the symbolic site, much in the same way as happened earlier this year at a coal-fired power station outside Washington DC. The organisers say they need about 2,000 people to take part if a full circle is to be formed. Oxfam is laying on coaches ("suggested donation £10") from cities such as Birmingham, Bristol, Cardiff, Coventry and Oxford to ferry people to the site. Once the Mili-band has been photographed in situ at 1.30pm, a "summer fete" will follow, say the organisers.

We're working to make the event as family-friendly and fun-packed as possible. So after we've formed the Mili-band there'll be a big summer fete. Complete with stalls, music, plenty to do for the children, and topped off with some inspirational speakers on climate change. Plus the Woodcraft folk who'll be bringing their fun bus as a base for outdoor games.

It will certainly be interesting to see how the event is policed following the disgraceful performance by Kent's finest at the Climate Camp last year. It's hard to imagine a repeat given the scrutiny and criticism that followed. It's also hard to see the police using the same tactics on members of, say, the Women's Institute. A formidable opposition, if ever there was one – and a group that has taken on the environmental cause with real zeal over the past year.
